To allcvhom'it may concern:

' Be itfknown that I, 'Gonnnnius A BRUSTER, a citizen of the United States, and a resident of Roslyn, in the county of Montgomery and State of Pennsylvania, have invented a certain new and useful Insulating- Support for Storage Batteries, of which the following is a specification.

The principal objects of the presentirb' vention are to. provide a comparatively inexpenslve, strong, acid resisting and efli- Icient insulating support. which can be readily put in under and taken out from under a I 6,;are'parts of thetanliii i I tank initially or inorder to renew'itsparts andlwhich can be adjusted ,to "compensate for inequalities the floor and which, when.

in osition,v has Parts against accidental displacement. I 'Another'iobject ofthe invent'on is to provide the-parts of such material and of such form that they are adapted to. do the work properly held required of them,-and that they are not subjected improperly to the stress of the load which theyfcarry and are therefore not liable to breakage.- I I 7 The invention will'be claimed at the end hereof, but will be first described in connection with the embodiments of it chosen for [Figure '1, 1s a side view of an insulating support complete, showing a portion of a tank. Fig. 2, is a-sectional view of the same but showing a slight modification, and Figs. 3 and 4 are perspective views illustrat in details of construction.

, n the drawings 1 is a pedestal of earthenware shown as flat on top. This part is made of earthenware, because" it must necessarily be high enough to keep the 'oil' 2 contained in the glass insulator 3, well above the floor, so that-water, as when the floor is washed, may not reach the oil by splashing, and it is not commercially practical to make-a pedestal of this height that will meet all the re' uirements of any other material.

The insulator 3 is made of glass and it could not be made of earthenware because the latter would becomd'soaked or permeated with acid or; acidu'lated water destroying its insulating qualities. The insulator 3 is cored out or hollow as at 4.

5, isa ca as of lead alloy that is placed pn top oft supper solid end of the insuator. I

, bending up one of the ends 10, it is ev that the parts 1' and 3 a relative lateral movenient.- The radiating? piece acts as a I Between. the flat top of thepedestal 1 d the bottom of the insulator. 3is placed a tering piece 7, of lead or lead allo 3* three arms 8 which {extendupwal hollow core 1 ,offthe insulator radiating arms '9,-the ends 10 (sf-which ay 7 be bent down onto the sides of thelb'ase.

can be separatedlby arms 9. give. athree-point support 'sojfltliat.. any inequality is taken up or compensated, forwithout putting such strains ontheped' estal-l or insulator 3 as would. tend tolbr k, or chip them. :Furthermorethe eenteiil igfl' lead pad. On top-ofthecag 5 and between it and the tank 6. there s placed a filling piece. This mayjconsistof one or more leaden washers 1l,.'which{trans fer the strain from the tank to the glassin-T sulator. These washers may be dished'in order to keep them stacked in central position. These washers operate as lead pads and prevent any improper transmission of 30 the strain. If the distance to be filled-by the.

filling pieceis considerable, itwould be expensive to use leaden washers, hence I provide a filling piece consisting of a porcelain disk 12 and a leaden tripod 13, the ends14 of which are folded back onto the face of. i

the filling piece 12 opposite to the face to which the tripod is, applied, thus the ends. 14 of the tripod come opposite the arms 15: thereof, so that the arms and the ends constitute a three-point support and leaden pad and thus protect the porcelain disk 12 fromsuch strains and stresses as would break, crack, chip or otherwise injure it. Combinations 'of these disks 12 of diflerent thicknesses and of the lead washers -11 can be used to make up any desired total length.

. Evidently the described combination of form, material and structure produces a unitary acid resisting structure which not only performs the function of insulating, but also performs the function of carrying a great load satisfactorily and efliciently, even iiaihough supported upon an uneven base or oor.

105 I do not claim herein the pedestal specifi- 'cally, since it forms the subject of my ap plication serially numbered 7 59,046.

What I claim is: '1. An insulating support for storage bat- 110.2. teries comprising the combination o f-.a,ped

' 'esta haviggaflat ten, a insulator haaiag'i v so i - a hollow core, a leaden centering piece having upstanding arms arranged to enter the' hollow core and arms constituting pads and foldable down overthe top edges of the pedestal, a cap on the insulator, and a "leaden filling piece on top of the cap, substantially as described.

2.- An insulating support for storage batteries comprising the combination of an earthenware pedestal having a flat top, a glass insulator having a hollow core, a

' leaden centering piece having upstanding copies of this patent may be obtained for teries comprising the combination of a p edestal having a fiat top, an insulator having 20 a hollow core, a leaden centering piece having upstanding arms arranged to enter the hollo'w core and arms constituting pads and foldabledown over the top edges of the pedestal, a cap on the insulator, and a filling 25 piece mounted on the top and consisting'of a leaden tripod and a porcelain body embraced by the alined arms of the tripod substantially as describedsigned my name.
